Review the engagement for security gaps

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden. It does disclose the core operation ('Read ... and report') which implies non-mutating behavior, and it enumerates exactly what it inspects. However, it does not explicitly state that the tool makes no modifications to the engagement, describe the output format of the report, or mention edge-case behavior such as when no engagement is active.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The English sentence is front-loaded with the core action ('Read the current engagement and report security gaps') followed by a compact, colon-delimited list of detection categories that earns its place by telling the agent what counts as a gap. The bilingual duplication doubles length but is justified for the JA/EN audience; still, it prevents a 5 for conciseness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a low-complexity tool (one optional enum parameter, no output schema, no annotations), the description covers the essential context: the operation, the target (current engagement), and a detailed taxonomy of what it detects. Minor gaps remain — the return value shape of the 'report' and behavior when no engagement is active are not described — but nothing critical is missing for correct invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% — the single optional `lang` parameter is fully documented in the schema with an enum, default, and bilingual description. The tool description adds nothing about parameters, so the baseline score of 3 applies; the description correctly refrains from duplicating what the schema already covers.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb+resource ('Read the current engagement and report security gaps') and enumerates six concrete gap categories (missing security stakeholder, ownerless severe risks, accepted risk without acceptor, missing deliverables, missing regulatory deadlines, missing disposal dates). This specificity clearly distinguishes it from siblings like review_all_engagements (all engagements vs. current), check_engagement_health (general health vs. security-specific), and gap_analysis (general gaps).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides clear context by scoping the tool to the current engagement and to security-specific concerns, which implicitly routes the agent away from review_all_engagements, gap_analysis, and check_engagement_health. However, it never names an alternative or states a when-not-to-use condition explicitly, so the exclusion logic is left to inference.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
